AB-RTC-TN-32.768KHZ-2-T1

AB-RTC-TN-32.768kHz-2-T1 is an ultra-low power Real-Time Clock (RTC) module with embedded 32.768kHz crystal, ABRTC-TNA-32.768kHz-2, uses an I2C communication interface to configure numerous features while sustaining temperature compensated frequency accuracy (±3ppm over -40°C to 85°C) in a compact lead-free ceramic SMD 3.2 x 1.5 mm package. These features include AEC-Q200 compliance, a periodic time update interrupt function, low voltage detection, external event input with interrupt and internal power-on reset function. The RTC has a broad operating power supply voltage range of 1.5V to 5.5V with low power consumption (240nA at 3V). Typical applications include IoT metering, industrial, health care and wearables/portables.
